Question
Solve the equation
a1=0,a2=21
Alternative Form
a1=0,a2=0.5
Evaluate
a3=2a4
Move the expression to the left side
a3−2a4=0
Factor the expression
a3(1−2a)=0
Separate the equation into 2 possible cases
a3=01−2a=0
The only way a power can be 0 is when the base equals 0
a=01−2a=0
Solve the equation
More Steps

Evaluate
1−2a=0
Move the constant to the right-hand side and change its sign
−2a=0−1
Removing 0 doesn't change the value,so remove it from the expression
−2a=−1
Change the signs on both sides of the equation
2a=1
Divide both sides
22a=21
Divide the numbers
a=21
a=0a=21
Solution
a1=0,a2=21
Alternative Form
a1=0,a2=0.5
